Perelman made a category of arguments that he termed to be "based on the structure of reality." Dr. Steven B. Katz joins us to discuss each of the arguments within this category, and how they rely on culturally accepted connections termed "liasons of succession" and "liasons of co-existence" in order to gain acceptance of other claims.  Essentially, you find structures of reality that are already there (already accepted) and then apply them to a specific situation. As Kenneth Burke points out, these structures may only be "natural" in the sense that a path made through a field is natural. Nevertheless, as soon as that structure or path has been made it is there as a structure that can be used to pass from A to B. This episode builds on the episodes "Chaim Perelman's Theory of Argumentation" and "Perelman's Quasi-logical Arguments."
